Targeting ultrasound for noninvasive diagnosis of brain cancer
Researchers at Washington University in St. Louis are developing a method to diagnose brain tumors using ultrasonic energy — and no incisions. Lead researcher Hong Chen has received $2.5 million from the NIH to pursue further study.
Novel imaging technology may help reduce biopsies for breast tumors
Scientists at Washington University in St. Louis plan to use a new imaging technique to get a better look at breast tumors and reduce unnecessary biopsies.
Noninvasive brain tumor biopsy on the horizon
Taking a biopsy of a brain tumor is a complicated and invasive surgical process, but a team of researchers at Washington University in St. Louis is developing a way that allows them to detect tumor biomarkers through a simple blood test.
Novel technique changes lymph node biopsy procedure for breast cancer patients
David Kilper/WUSTL PhotoFor the first time, WUSTL scientists have used gold nanocages to map sentinel lymph nodes in a rat noninvasively using photoacoustic tomography.
Novel technique changes lymph node biopsy, reduces radiation exposure in breast cancer patients
David Kilper/WUSTL PhotoWUSTL biomedical engineers Younan Xia (left) and Lihong Wang examine the photoacoustic tomography machine (PAT) in Wang’s Whitaker Building laboratory.Information obtained from a new application of photoacoustic tomography (PAT) is worth its weight in gold to breast cancer patients. For the first time, Lihong Wang, Ph.D., Gene K. Beare Distinguished Professor in the Department of Biomedical Engineering, with a joint appointment in Radiology, and Younan Xia, Ph.D., James M. McKelvey Professor in Biomedical Engineering, with a joint appointment in chemistry in Arts & Sciences, both at Washington University in St. Louis, have used gold nanocages to map sentinel lymph nodes (SLN) in a rat noninvasively using PAT.
